i v JP3 ua zaai A 4 awrzff messes shovvn -in Figs. 4 to 6 thesieve is also in the form of a truncated cone part es and a iiat.-

ring part c4. These parte are carried by a shaft fr. supported in bearings avhicb. rest on the iiooring an; vthis flooring 1s arranged over the duct a through which the water to be filtered asses. The dotted line a. represents the highest point to which the Water isI likely to rise in the duct a and-it will be seen that the yfront erforated late or sieve c* extends up to t is'rline. he rim a4 of the sieve c3 rests against a face plate fra on the duct a. As in the prior forms described plates f areA rovided on the sieve which act simultaneous v as'blades to carry off the mud or the like ltered frorn the Water and as strengthening ribs. The blades f2 are provided at their'ends with rubber bands fs which are adapted to bear against the outside of a fixed housing o. The housing-ois not shown in Fig. 4 but from Fig. 5 it will be seen that this housin is continued around the sieve from the floor evel. It may however, if desired] be continued for a greater distance. At the upper part of the housing o conveniently the highest point, a ho per g2 is arranged to receive the `mudv and t re like discharged from the blades f and conduct the same to a Wagon w which .is conveniently run on rails extending inside the sieve as shown.

The movable nozzles 7L and h2 are referably arranged as shown op losite the iopper g2. The method in which t ie necessary inotion is transmitted to the nozzles h and h2 is illustrated in Figs. 7 and 8 A rotating shaft u is provided with a crank 'e' which connects throuvh' a rod u2 to an oscillating lever ua. The Iever 11.3 is pivoted at its center and is provided with two slots in which there engage the ends of rodst and t3. The rod t is also rovided with slots in which there engage t ie ends of rods t pivoted at t?. The rods t carry at their opposite extremities the nozzles h2 shown as two in number which are adapted to move over the conical part c3 of the sieve. The extremity of the rod 3 which is pivoted at t* is adapted to carry the nozzle h" which is arranged to move over the ilat front plate c4.

The nozzle which I prefer to employ is preferably of the shape seen in side view in ig. 1, see h, and in plan in Fig. 2. In this form of nozzle the air passes out in a thin broad stream Which has, what might be called, a cutting action on the materia With in the meshes of the filter. As can be seen from Figs. 1 and 2 the nozzles h are held in a position With the broad direction of the stream at right angles to the axis of rotation of the sieve. This arrangement is, I find, the one best calculated to produce successful results.
